Abstract: To investigate the effect of sampling position on intramuscular lipid content and fatty acid composition of pork, the muscles from four carcass positions of Rongchang pig breed were measured for their lipid content, fatty acid composition of total intramuscular lipids, phospholipids and triglycerides and free fatty acid composition. The results showed that significant differences in intramuscular total lipid content and triglyceride content were observed among four positions (P <0.05), while phospholipids and free fatty acids showed no significant difference (P > 0.05). In addition, the differences in the fatty acid composition of intramuscular total lipids and free fatty acids among four positions were significant (P< 0.05), while no significant differences in phospholipids or triglycerides were observed (P > 0.05). The effect of free fatty acids on fatty acid composition of intramuscular total lipids was very limited due to its low percentage in intramuscular lipids, so the significant differences in intramuscular total lipid content and fatty acid composition among four positions of Rongchang pig was mainly caused by the difference of intramuscular triglyceride content.

Key words: pork, position, intramuscular lipid, lipid content, fatty acid composition
